A way to define multiple exponents stacked onto each other. Used in many ways: To overcomplicate tetration notation for no good reason in particular To express tetration in a broader sense. If the number is ³5 (scary isn't it), it's just 5⁵(⁵), or even better, 5³¹²⁵, NOT 5²⁵ To scare calculus students into submission with e^x derivatives, e.g. e^e^e^e^3x² To have just a little bit of fun when writing a weird and complex exponentiation function Also used to troll people when asked how to use exponents, i.e. calling them a dumbass without directly saying it to them
